摘要
应用齐次平衡法获得了 2 +1维扩散长水波方程的B cklund变换和一个线性偏微分方程 .从线性偏微分方程出发得到了 2 +1 维扩散长水波方程的多孤子解和单孤子解以及其它精确解 ,分析单孤子解 。
Using homogenous balance method an auto Bcklund transformation of (2+1) dimensional dispersive long wave equation and a derived linear partial differential equation are obtained. As a result, the multisoliton and single soliton and other exact solutions of (2+1) dimensional dispersive long wave equation are derived from above mentioned differential equation. By analyzing single soliton solution, some dromion solutions are obtained.
